[SLP]Improve analysis of copyables operands for commmutative main instruction 
For commutative copyables, instruction operands are always LHS and other
are RHS. But if some instruction is main and has 2 instructions
operands and RHS is more compatible with LHS operands, than LHS
operands, need to swap such operands for better analysis.
